Fixed inductors are a type of electronic component that store electric energy, called inductance, in an electrical circuit. The SPM3020T-2R2M-LR is a surface-mount, high-current inductor that is specifically designed for the needs of the power supply, lighting and automation markets. It features a higher inductance rating than the more common SPM3020 series and the LR design offers a power output which is twice the current rated value.

The SPM3020T-2R2M-LR possesses a wide range of features and capabilities that make it suitable for a variety of applications. Its inductance range is 0.2uH, its rated voltage is 200VAC, its current rating is 10A, and its insulation voltage rating is 3000VAC min. The SPM3020T-2R2M-LR also features an industry standard packaging in a 2.2 mm profile and an external shield that helps minimize noise and leakage inductances which makes it perfect for use in power supplies, lighting applications and other applications where high inductance and low noise levels are desired.

When it comes to its working principle, the SPM3020T-2R2M-LR can store energy through the product of the self-inductance of the component and the current which is flowing through the circuit. In a circuit with a fixed inductor, when current is passed, a magnetic field will be generated around the inductor. This field will then induce a counter electromotive force which will oppose the current based on Lenz\'s law. This indicates that when the current through the circuit increases, wherein more energy is introduced into the circuit, the induced EMF will resist the increase in current. A decrease in current will induce a reactive EMF that will attempt to restore the current back to its original level.

The SPM3020T-2R2M-LR is a high-power inductor that has been specifically designed for maximum power output and minimum noise levels in power and lighting applications. Its wide range of features, such as its large inductance range and its high rated voltage, make it suitable for a variety of applications. In addition, its working principle makes it well-suited for electrical and electronic applications where high current and high inductance are desired. As such, the SPM3020T-2R2M-LR makes an excellent choice for a variety of industrial and automotive uses.
